Abstract :

Background: The Global Burden of Disease Study projected that COPD, which ranked sixth as a cause of death in 1990, will become the third leading cause of death worldwide by 2020; a newer projection estimated COPD will be the fourth leading cause of death in 2030. Tobacco smoking continues to be a major cause of COPD. However, tobacco smoking is not the only cause of COPD, and it may not even be the major cause in some parts of the world. Epidemiological studies show that 5-12% of subjects with COPD are nonsmokers. Very little is known about the clinical, radiological and pathophysiological features of fixed airway obstruction in these subjects. Another reason to study COPD in non-smokers is that it might illustrate what other factors are important. This study is an attempt to study the clinical profile and the risk factors other than smoking in patients with COPD. Material and methods: Patient who met the inclusion and exclusion criteria pulmonary function testing was done using hand held PC based spirometer, model: RMS- HELIOS 401. Considering acceptability and repeatability criteria three satisfactory efforts were recorded and best effort was considered. Bronchodilatation was done using 200 μg of inhaled salbutamol using a metered dose inhaler and spacer and test was repeated after 15 min. Standard statistical method for data compilation and analysis,tables,charts,graphs and text.Software package like SPSS applied for statistical analysis. Results: One hundred and two cases were studied. All patients were never smokers. Multiple environmentally hazardous parameters other than smoking were used as tool and analysed accordingly. Spirometry reading data were collected and analysed. Gold severity staging established. Conclusion: In the study it was found that although occupational exposure and air pollution were not associated with increased risk of COPD, prevalence of COPD among non-smokers was more common in female population from the rural areas.
